EuroPython 2011 - How to build complex web applications having fun?
The document discusses the challenges and fun aspects of building complex web applications, emphasizing the importance of architectural decisions and community support in the development process. It highlights two contrasting project examples: a problematic public sector project and a successful startup project in the bottled water industry, detailing the different organizational structures and technologies used. The talk also includes insights on using specific frameworks and tools, like Pyramid and SQLAlchemy, for effective software development.
